H - section steel is a new economic construction steel. The shape of h-section steel section is economical and reasonable.Mechanical properties ofGood, rolling on the cross section of each point is more uniform, the internal stress is small, compared with ordinary i-steel, has the advantages of large section modulus, light weight, saving metal, can reduce the building structure of 30-40%; And because of its leg inside and outside parallel, leg end is a right Angle, assembly assembly into components, can save welding, riveting workload of up to 25%. It is often used in large buildings (such as workshops, high-rise buildings, etc.), Bridges, ships,Hoisting machinery, equipment foundation, support, foundation pile, etc
